To all wtomitmay maniaci/'ailA l. v o f Be it known that l, JonN'lPg-Donam a citiduLac and State ol Wisconsin, have invented newandvuselul Improvements in Driving vhllechanism lor Flashingllllachines9 ol which the lollowing is a description, relerence being `had to the accompanying drawings, which* areapart ol this specihcation.

g'lhe invention relates to; driving mecha' `mism., and `more particularly to a driving mechanism loria washing machine.

.lt is oneol the objects ol this invention to provide a-drivingfmechanism lor operating the shalt carrying theclothes pounder so 4as to produce several agitations and vertical reciprocationsrol vthe pounderv in vone direc-f tion and thenbyreversing the direction ol lll turning ol the' drive shalt" .produce several f agitations andvertical Areciprocations' ol the dll . ing the invention pounder in the opposite direction with the result lthat the,pounder,- duringthe' washing operation, `will 'striheftheclothes inl diderent places and thuseciently Awash them;

- A lurther object ol the l*invention is to provide a bearing lor, thel `pounder shalt which will enablesaid shalt to'be vertically reciprocated without interlerence vwith the so called apronusually di p'oundervshalt.,v

struction, said cover carrying a` bracket l in whichthe pounder shalt 8 is verticallfy` slidably and pivotally mounted, said sha carrying a pounder 9ct any suitablekv construction. .a horizontal shalt l0 is secured tothe tub and hasl a dy wheel Y' 1l mountedv thereon provided with a groove l2 in which around rubber band ld is inserted and 4which band is adapted to be lrictionally engaged by the wheel ola motor (not shown). 'lhe construction above described serves to continuously rotate the wheel ll however anyother suitable means may be used to impartmovement to the wheel ll. l Fach lorm ol the invention includes a horizontally disposcd'drive shalt ll yournaled in? the bclret l, adrivin connection between the shalts t and ll, and a driving "connection between the shalt it and wheel the wheel 1d Y ln Figs. il and d the driving coection between the shaltsV e and lt consists ol an arm ori cranh l5 secured to the shalt e and 'having a sphericallmiob lb slidably and pivotally mounted inthe bore ll ol a cranlr l@ connected to the shalt lll-to provide an o-L set joint coection with said shalt. 'lhis odset joint connection reduces a bach and lorth or agitating movement ol the pounder `shalt together with an up and down movement thercol on `the rotation ol the yshalt lll. ln order to relieve the pounder ol excessive load l have provided a yielding connection lbetween the' driving connection and the shalt ll which is lormed byl slidably mounting the same hind el oset cranh connec- Ying the crank i8 in a bore i9 in a member 2U -mountedon the shalt ll and interposing a y a ide r 22 anda guide tion but instead ol the crank i8 l ount a vgear 2l on the shalt 8 an provide' a segmental-gear 25 pivotally mounted. en arme ltd 256 on the shaft 8 and connected with said gear 24, with a cylindrical arm 25 pivotally and slidably mounted in the bore 17 of the crank 18. This construction also produces an agitating movement and vertical reciprocatory movement of the pounder shaft on the rotation of the shaft 14.

In Fig. 5 I have shown a driving connection between the shafts 8 and 14 showing a different manner' of yieldingly connecting the crank on' shaft 8 to that on the shaft 14. In this instance the crank 18 is directly connected to the shaft 14 and providedv with a bore 17 in which the rounded end 16 of a two part crank 15', 15, secured to the shaft 8 is slidably and pivotally mounted. y This two part crank comprises the part 15 secured to the shaft 8 and the part 15 pivotally secured `to the part 15 and yieldingly movable downwardly with respect thereto by means of a spring 21 secured at its ends to the parts 15' and 15. respectively. Like the other constructions this permits relative yielding movementof the pounder shaft 8 and agltates the said shaft in the same way as the 'construction shown in Fig. 1.

In each instance the means for reversibly driving the shaft 14 consists of an automatically reversible gear drive connection `between the shafts 14 and 10. rIhis comprises a member 27 journaled on a stud shaft 28, a gearing connection between said mem-1 ber 27 and the shaft 14, and means for continuously driving said member.

` The gearing connection between the member 27 and the shaft 14 consists of a seg mental bevel gear 29 on Ithe member 27 adapted to work with either of two oppositely disposed bevel gears 30 and 31 on the shaft 14.

rIhe means for driving the member 27 consists of a bevel gear 32 formed in the member 27 working with a bevel gear 33 loosely mounted on the shaft 14 and carrying a spur gear 34 meshing with a spur gear -35 carried by the Hy wheel 11. 0f course it will be understood that any suitable means may be provided for driving the member 27 to impart continuous rotary movement thereto. v

iWith these constructions the rotation of the shaft 14 will produce several agitations of the pounder in one direction and then several agitations in the reverse direction during the vertical reciprocations of the pounder shaft 8, the reversal of the drive of .the shaft 8 being accomplished by the alternate engagement of the gear 29 4with Athe gear 30 and 31, the gear 29 being continuously driven. Since the pounder is alternately agitated for about a half revolution on either-side of its mid position it strikes the clothes in did'erent places during terasse obviate the necessity for the reversal of the apron and to permit free movement of the pounder shaft without interference with the apron I have provided a hollow bearing shaft 36 secured to the bearing arm 37 of i the bracket 7 ,"which shaft telescopes within the hollow pounder shaft 8 so that said shaft will not project above the arm 37 at its extreme upper position. The shafts 36 and 8 are made hollow because of the usual valve, not shown, which is carried by the pounder,

I am aware that 'the details of construction herein shown and described are subject to some modiiication and change and I desire it to be understood that such changes as come within the scope of the a pended claims, I deem to be within the spirit of my; inventiono What I claim as my invention is:

1. In a driving mechanism, the combination, with a vertical shaftof a drive shaft disposed at an angle thereto, a driving connection between said shafts for imparting several oscillations and vertical reciprocations to said vertical shaft, and means` for turning said'drive shaft several times in one direction and then 'in the opposite direction to reverse the oscillations of the vertical Shaft.

2. In a driving mechanism, the combination, with avertlcal shaft, of a drive shaft disposed at an angle thereto, a driving connection between said shafts having an offset joint connection with one of said shafts, and means for automatically reversing the direction of rotation of the drive Shaft after several rotations thereof.

3. In a driving mechanism, the combination, with a vertical shaft, of a drive shaft disposed at an angle thereto, a driving connection between said shafts having an offset joint connection with said drive shaft, a member continuously driven in one direction, and a reversible gear drive connection between said member and the drive shaft.

4. In a driving mechanism, the combination, with a vertical shaft, of a drive shaft disposed at an angle thereto, a driving connection between said shafts for oscillating and vertically reciprocating said vertical shaft on the rotation of the drive shaft, a

t shaft continuously driven in one direction, a

segmental gear mounted on last named said shaft, a pair of gears on the drive shaft adapted te aternetey mesh with seid seg menta gear for alternately retailing Said drive shaft in opposite directions.,

5 h1 a driving mechanism, the combination or" a bracket having am upwardly projecting bearing arm, e hollow pounder shaft vertically slidably and pvotsrlly meunrec in said bracket, a bearing shaft depemdmg from said erm and edapfee 'im telescope Within the hell-ew of seid peunder smit, and ML means fer agita-ting and vertically recilpre caring said pounder shaft.,
